Altitude App
Compare device-based altitude with a terrain-model elevation estimate.
Useful for rough elevation context on compatible devices
Selectable sources, units and a target altitude make differences visible.
Keep in mind: GPS vertical error and terrain-model resolution can be substantial; 30-meter horizontal resolution is not guaranteed vertical precision.
